This language model follows a mirror-based design; see
Gilad Bracha and David Ungar. Mirrors: Design Principles for Meta-level Facilities of Object-Oriented Programming Languages. In Proc. of the ACM Conf. on Object-Oriented Programming, Systems, Languages and Applications, October 2004.In particular, the model makes a distinction between static language constructs, like the element representing
java.util.Set, and the family of
 types that may be associated
 with an element, like the raw type java.util.Set, java.util.Set<String>, and java.util.Set<T>.
  Unless otherwise specified, methods in this package will throw
 a NullPointerException if given a null argument.
